my improved construction. Fig. 2 is a side elevational view of the bolster seen in Fig. 1,

` and showing the center vsills and side sills of the underframe in section. .Fig 3 is a vertical sectional View taken approximately on the line 3 3 of Fig. 2. Figa is a cross sectional view taken approximately on the line 4--4 of Fig. 3. v

This invention relates generally to railway car underframes, and `more particularly to theconstruction of the body bolster and the end portion of the center sill.

The principal object of my invention is to slot the end portion of the center sill or sills and to form an openin or openings through the central portiono the body bolster in order that the end portion of the center sill can be combined with the lbody bolster so that said center sill rojects a substantial distance beyond the body bolster, thereby forming an interlocking connection which can be easily assembled, or in the case of re-' pairs can be easily taken apart. By slotting `the end portion of the center sill, it is possible to locate the bolster a short distance in from the end of said center sill, and the projecting portion of the center sill serves as a .point of attachment for draft sills which extend to the end sill of the underframe, and which draft sills are practically continuations of the center sills.

To the above purposes, my invention con- J sists in certain novel features of construction and arrangement ofv partshereinafter more fully described and claimed. y

In the construction of the underfrarne as shown, I employ a pair of center sills, each comprising a vertically disposed' web plate 10, to the upper and lower edges of which 4 17 is a center bearing 19.`

so that theirhorizontal flanges are out wardly presented. Positioned on top of the center sills thus formed; is a cover plate 12, the edges of which are attached to the horizontal flanges of the upper pair of angles 11 by meansof rivets.

The web plate 10 of the center sills are provided in their end' portions with longitudinally disposed slots 13, which slots are for the accommodation of the top fiange of the -body Abolster forming a part of the underfrarne.'A This body bolster is preferably cast in a single piece and comprises a verti- I callydisp'osedweb 14:, a top flange 15, and a bottom lange 16, and thus said bolster is substantially of Isbeam shape in cross section. The vertically disposed webs 140i the bolster are sometimes designated intermitted diaphragms which are providedv with openings for the passage of train pipes, etc. y The central portion of the body bolster is preferably depressed with. respectl to its ends and the central portion of the top flange 15 occupies the inner ends of the slots 18. The length of these slots is approximately twice the width of the top flange 13, so that when the body bolster is properly assembled with the center sills, the ends or' the latter project a short distance beyond the body bolster. Openings 17 are formed through the web 14 of the bolster at points on opposite sides of the center thereof, which openings accommodate the lower portions of the web plates 1 0 and the/lower pair o i" angles 11.

Formed integral with the web 14 andarranged at right angles thereto immediate adjacent thc inner edges of the openings 17 are web plates 18, which lie immediately against the vinner faces oi the webplates 10, and these parts are rigidly fixed to eachother by means of rivets 19a or like fastening devices. r

Formed through the center of the body bolster is the usual verticallydisposed opening 20 for the accommodation of the center pin and formed integral with the underside of tbe bottom flange lbetween the bottom flange i6v tothe Asides oi? the' center bearingvand beneath vtheopenings 17 are 'short reinforcing ribs 20"; which are for the are fixed angles 1l, the same being arranged ll purpose of strengthening that portion of the lili) openings l vthe ends of chains or cables utilized for pulling cars about While the same are in the yards or upon side tracks.

Formed integral with the bolster near its ends and on both sides thereof are outwardly projecting horizontally disposed flanges 25 which are adapted to receive nailing strips, and formed integral with the bo-ttom flange 16 adjacent to these flanges 25 are side bearing plates 26.

In assembling the parts of the underframe, the bolster is positioned on the center sills with the central portion of the top ange 15 positioned in the innerV ends of the slots 13, and the portions of the center sills beneath the slots 13 project through the openings 17. Rectangular filler 'plates 27 are now applied to the outer faces of the Web plates 10 between the edges of the vertically disposed langes of the angles 11, which filler plates extend from the front edge of the top flange 15 to the ends of the web plates 10. Positioned directly againstthese filler plates and against the end portionsof the vertically disposed flanges of the angles 11 are the inner end portions of draft sills 28 preferably channelshaped in cross section, and said vdraft sills are directly connected to the center sills by means of rivets or like fastening devices, the same passing through the filler plates and the vertically disposed webs of the angles 11. The outer ends of the draft sills 28 are attached in any suitable manner to the end sill 29 of the underframe. By depressing the central portion of the body bolster the tops of the side sills 23 fixed to the ends of said bolster occupy substantially the same horizontal plane with the top plate 12 that is attached to the center sills. By slotting the center sills to accommodate a portion of the body bolster and attaching the inner ends of the draft sills/ to the ends of the ce1 er sills, Which project beyond the body bolster a very simple, strong and rigid construe tion is produced and the parts enteringinto such construction can be easily assembled or, in the case of repairs it will` be a com i paratively easy matter to remove the draft sills, thereby permitting the body bolster to be easily and quickly remo-:ed from lh center sills. l

It Will be readily understood that minor changes in the size, formr and conslrluztion of the various parts of my improvedl underlrame, can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scopeof which is set forth in the appended claims.
